weight of evidence
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Principles of method if other than guideline:
- Principle of test: Diferential Scanning Calorimetry
GLP compliance:
no
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
155.47 °C
Atm. press.:
ca. 1 atm
Decomposition:
no
Sublimation:
no
Conclusions:
The melting point of the test item was determined to be 155.47 ± 0.06 ºC.
Executive summary:

A differential scanning calorimetry test (DSC) was performed to determine the melting point of the test item. Around 5 mg of test item were weighed in non-hermetic aluminium capsules and studied by differential scanning calorimetry over a temperature range extending from T = 293.15 K to the melting point temperature of the sample, with a heating rate of 1 K/min. All determinations were performed in a dry-nitrogen atmosphere. Based on the test results, the melting point of the test item is 155.47 ± 0.06 ºC.
